Senior Software Engineer, IAM

Docker has been one of the most loved brands in developer tooling, trusted by more than 20 million monthly users and over 20 billion container image pulls. From solo founders to the world's largest companies, developers rely on Docker to build, share, and run their applications across our suite of products including Docker Desktop, Docker Hub, and Docker Scout. We are a globally distributed, remote-first team building the tools that define how software gets built and delivered. As AI agents redefine software development, Docker is at the center of that shift, providing the sandboxed environments, verified images, and secure infrastructure that make autonomous workflows trustworthy by default. We're looking for a Senior Software Engineer to join our IAM team. The IAM team owns Docker’s identity backbone: the systems that determine who a user is, what they can do, and how organizations govern access at scale. Every authenticated request to Docker depends on these services—making their correctness, latency, and security foundational to customer trust. The team owns authentication and authorization, access tokens, OIDC, SSO, and SCIM, and user and account management systems, along with supporting enterprise services. You'll work on systems used by millions of developers and the world's largest organizations, with the governance controls enterprise customers require. This is a high-impact role for an engineer who enjoys deep backend work in a space where correctness, latency, and security all matter - and where the design decisions you make today shape how Docker scales identity for years to come. Responsibilities Design, build, and operate Go services powering authentication, authorization, token handling, and identity lifecycle across DockerExtend OIDC, SSO, SAML, and SCIM integrations, and evolve our authorization model (including ReBAC) as permissions scale across products and tenantsImprove observability, performance, and security posture of identity services on the hot path of every authenticated request, and strengthen audit loggingDesign for multi-region operation, graceful degradation, and safe rollout of changes to critical auth flowsLead projects end-to-end, contribute to technical design and long-term direction of the IAM platform, and mentor teammates in identity and security domainsPartner with Product, Security, and engineering teams that depend on IAM primitives to ensure our APIs are clear, safe, and easy to adoptThis role may require participation in an on-call rotation to provide support outside of standard business hours, including evenings, weekends, and holidays, as needed. What You'll Work On Beyond steady-state ownership of our identity services, you’ll help shape the next phase of Docker’s IAM platform, including evolving our authorization model for fine-grained, cross-product access, expanding support for enterprise identity integrations, and improving the reliability and observability of systems on the critical request path.
